The public smoking ban has put the Dutch "coffee shop" in a quandary; people can still smoke cannabis joints but cannot blend it with tobacco.
The Netherlands, which tolerates the use of "soft" drugs, will banish tobacco smoke from restaurants, cafes and other public places from July 1.
But as it follows the example of other European Union members in curbing smoking for public health reasons, the country finds itself in a singular position as the only one to allow, since 1976, marijuana use in licensed cafes.
While the new law does not prohibit the smoking of cannabis in coffee shops, owners are coming up new strategies to stay afloat in a country where users traditionally prefer their cannabis joints mixed with tobacco.
The Any Day coffee shop in Amsterdam has introduced a novel gadget that produces a new kind of high to keep his clients' attention.
The machine, like vaporisers sometimes used for medicinal purposes, works like a water pipe but without combustion. It transforms the cannabis into vapour, which is then inhaled.
With no tobacco and no paper, "the vapour broadens the user's thoughts without rendering him apathetic," explained its creator Evert, who did not want to give his full name.
"People thank me for having changed their lives."
The pub "Cremers" in The Hague, which allows patrons to smoke cannabis at the bar counter, is planning a segregated smoking section to comply with the law and keep its clients happy.
